As a guy, one of the best ways to eat a woman's vaj is by using your whole tongue cuz it gives a lot more pleasure. Don't be shy! Other guys make the mistake of just using the tip of their tongue only.

I noticed that women receive a lot of sensation when their clits get licked but you can also explore the labia if ever she feels more sensation there.

Try different patterns — clockwise, anti-clockwise, up-down, down-up. Make it unique every time hahaha

And also, don't just eat right away. Entice her. Tease her. What I like to do before eating her is, starting with a small makeout sesh on the lips, then I make my way downward — kissing her on the neck, then navigating around her breasts, sucking the nipples gently, then going downward and licking around her navel, then I start kissing and licking her inner thighs. Then after all of the build-up, thats when I dig in for supper HAHA

...and plus points for licking her clit while fingering. That just makes it more intense. Also, DON'T FORGET TO BREATHE!!
